The article presents the results of the experimental study of the peculiarities of the work under the calculation load of planar
superstructural plates of the developed system of non-beating overlap. Great attention is paid to the construction of bearing
structures prototype. The design of auxiliary equipment is described, which enabled to test the investigating U-block in conditions
that imitate real resistance. The method of performing experimental research with indication of methods and means of
measuring geometrical and physical parameters that characterize the stress-strain state and bearing capacity of the test plate is
given. The conducted investigations enabled to determine the nature of deformation and destruction of the superstructure
slabs as a separate element in the developed system of non-beating ceiling. Attention is drawn to the fact that the achievement
of the bearing capacity is not accompanied by the process of destruction, but is characterized by significant movements
of the supporting plots in the vertical plane
